I've used plex for years and absolutely love it,in general and for the longest time I haven't been able to recommend it highly enough. I also use it to stream family home movies and obscure movies/tv shows for friends and family (I was terrified at first but you absolutely can use the managed users features and ensure that specific accounts ONLY see the specific libraries you want them to see)
Sadly, they have continued trying to kill the plugins and I think Plex broke the metadata agents last year BUT you can add it by hand with custom .nfo files now... It's not the end of the world but annoying when I want to quickly determine what actor I'm seeing/what other vids they're in and so on... Anyone else still using Plex? and if so are you able to get the metadata agents working still?
